hi there mate, as johnny g said yes you can, there's several members here who have done it and have some pretty good results with it. Do you have a N/A supra? The general consensus is that it's not worth converting a N/A to a turbo purely for financial reasons, by the time you've uprated the transmission to deal with the power and then the increased insurance you're heading towards the money for a tt auto. If you have a 6spd N/A it becomes a much better option, as the 5spd box will give up after a while at the average NA-T power level. Then if you want to push the power up you have to lower the compression either by a thicker headgasket or turbo pistons. Dr_jekyll on here would be the man to talk to if your serious about it. And have a good search, there's loads of information kicking about the place
